PURPOSE: To examine the efficacy, predictability and safety of posterior chamber phakic intra-ocular lens implantation in patients with hyperopia. METHODS: The authors analyzed retrospectively 16 patients (31 eyes) submitted to the implantation of a posterior chamber phakic lens for the correction of hyperopia. RESULTS: The mean preoperative spherical equivalent manifest refraction was +5.39D (ranging from +1.25 to +10.50D) and cycloplegia refraction was +6.44D (ranging from +3.25 to +10.75D). The mean postoperative spherical equivalent at the last visit was -0.44D (ranging from -2.75 to +1.25D). On comparing the preoperative and postoperative corrected visual acuity the results showed that three eyes (9.7%) lost one line of visual acuity, 19 eyes (61.3%) kept the same preoperative corrected visual acuity. Six eyes (19.3%) gained one line of visual acuity and three eyes (9.7%) gained two lines. Regarding complications, in 13 eyes (41.9%) a mild amount of pigment deposition on the phakic IOL anterior surface was observed and three patients (18.7%) had complaints of glare. CONCLUSION: Posterior phakic lens is an effective, predictable and safe method for the correction of mild to severe hyperopia. Visual acuity improvement was significant and a longer follow-up will help to better address long-term stability of the results and the incidence of complications.
